The correlation between viral infection and fetal microcephaly was revealed in 2015, yet we still lack a vaccine against ZIKV. Here, we present a genetic vaccine that delivers the premembrane (prM) and envelope (E) genes of ZIKV using a recombinant baculovirus vector that expresses a human endogenous retrovirus (HERV) envelope on its surface to enhance gene delivery. We observed that baculoviruses with HERV envelopes (AcHERV) exhibited specifically higher gene transfer efficiency in human cells compared to the wild-type baculovirus vector. Using the AcHERV baculovirus vector, we constructed a recombinant baculovirus vaccine encoding ZIKV prM\/E genes (AcHERV-ZIKV), which are major targets of neutralizing antibodies. Mice immunized twice with AcHERV-ZIKV exhibited high levels of IgG, neutralizing antibodies, and IFN-\u03b3. In challenge tests in IFN knock-out mice (A129), AcHERV-ZIKV showed complete protection in both challenge and pregnancy tests. These results suggest that AcHERV-ZIKV could be a potential vaccine candidate for human application.<\/jats:p>","DOI":"10.3390\/vaccines9050438","type":"journal-article","created":{"date-parts":[[2021,5,1]],"date-time":"2021-05-01T21:35:39Z","timestamp":1619904939000},"page":"438","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["The Safe Baculovirus-Based PrM\/E DNA Vaccine Protected Fetuses against Zika Virus in A129 Mice"],"prefix":"10.3390","volume":"9","author":[{"given":"Hanul","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Bioindustrial Technologies, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jungmin","family":"Chun","sequence":"additional","affiliation":[{"name":"Center for Glocal Disease Control, KR BioTech, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mina","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suyeon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nahyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hee-Jung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minjee","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8553-2107","authenticated-orcid":false,"given":"Ha Youn","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Kyoung","family":"Oh","sequence":"additional","affiliation":[{"name":"College of Pharmacy and Research Institute of Pharmaceutical Sciences, Seoul National University, Gwanak-gu, Seoul 08826, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young Bong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Bioindustrial Technologies, Konkuk University, Seoul 05029, Korea"},{"name":"Center for Glocal Disease Control, KR BioTech, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"121","DOI":"10.1146\/annurev-med-040717-051127","article-title":"Zika Virus Vaccine Development: Progress in the Face of New Challenges","volume":"70","author":"Diamond","year":"2019","journal-title":"Annu.
